Thread: using a Void Function?

Im new to C programming, so bear with me. I've created a couple of functions, but have never used one of the void type.
Eventually I will have it draw a rectangle that displays 1 character across for every unit of width, and the same for the height, but first I just want to get the syntax correct just to make it print one character. Basically I just want to know how the void function works and understand how to use it.

Code:

void drawRect (int width, char character);    /*prototype*/


printf ("%c\n", drawRect (width, character) );   /*function call*/



void drawRect (int width, char character)       /*function*/
{
	if (width > 0)
	{
		printf ("%c\n",character);
		
	};
	
}

These are all in the correct places in the code, because my other functions are working properly. When I compile, I keep getting this error 'printf' : actual parameter has type 'void' : parameter 2.

Thanks.

This is for a class, so our handout specifically says to use void....

void drawRect (int width, int height, char character)

If this isnt going to work, what are some examples of why you would use void?

A guy at work explained it to me. All I had to do was use this: drawRect (width, character); as the function call, and eliminate the whole printf line.

Thanks, quzah, now that I know how to do it your post makes sense. The problem is this is my first programming class and when I read your post I didn't really understand what you were telling me.

Anyway it works now.
